Filed:

Dec 27, 2004

Appl. No.:

11/023235

Inventors:

Davin R. Lee - Watertown WI, US

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

H01H 13/00
H01H 3/00

US Classification:

200339, 200 5 R, 200553

Abstract:

An actuator subassembly is for a rocker switch. The actuator subassembly forms a self-contained unit removably inserted within the rocker switch to define the operating characteristics thereof. The actuator subassembly includes an operating member operable between a plurality of positions, an extension and a spring-biased plunger. A shaped member which is pivotally coupled to the operating member includes a plurality of shaped sections each corresponding to one of the positions of the operating member. Each shaped section has a profile which is designed to provide the desired rocker switch operating characteristics, such as the type of action of the operating member and the operating force for the operating member.

US Classification:

200449, 200559, 200339

Abstract:

An actuator assembly is for a short-depth rocker switch including a housing having an opening, a cavity, a base, and a first depth between the opening and base. The actuator assembly includes an operating member having a first end disposed proximate the opening, and a second end extending into the cavity, and, an over-center mechanism disposed proximate the first end of the operating member, distal from the second end of the operating member. The over-center mechanism comprises a one or two-piece shaped element which defines a plurality of operating characteristics of the operating member, and which has a second depth which is less than about 25 percent of the first depth of the housing. This enables the overall depth of the rocker switch to be relatively short in comparison to known designs. A sensor for detecting the position of the second end of the operating member is also disclosed.

International Classification:

G01R 33/06

US Classification:

324117R, 324117 H

Abstract:

The present invention is directed to a system for current sensing including a first Hall effect sensor and a second Hall effect sensor constructed to provide feedback indicating current flow through a conductor susceptible to external magnetic flux. A housing is configured to position the first Hall effect sensor and the second Hall effect sensor about the conductor to provide generally magnitude equal feedback of the current flow through the conductor and generally polarity opposite feedback of the external magnetic flux.

International Classification:

H02H 9/02

US Classification:

361 42, 361 931

Abstract:

A battery disconnect includes a housing, battery and load terminals, separable contacts electrically connected between the battery and load terminals, an operating mechanism structured to open and close the contacts, and a manual operator cooperating with the operating mechanism to open and close the contacts. A current sensor is structured to sense current flowing between the battery and load terminals. A circuit cooperates with the current sensor and the operating mechanism to trip open the contacts responsive to arc fault, overload and short circuit conditions associated with the sensed current. The circuit includes a first input structured to receive a remote on/off signal and a second input structured to receive an inhibit signal. The circuit cooperates with the operating mechanism to open and close the contacts responsive to the on/off signal, and to inhibit detection of the arc fault, overload and short circuit conditions responsive to the inhibit signal.

International Classification:

H01H 23/00

US Classification:

200339, 200315

Abstract:

An actuator subassembly is provided for a rocker switch including a housing, a plunger and a number of contact elements. The actuator subassembly includes an operating member movably coupled to the rocker switch housing at or about an opening, and including at least one projection which extends into a cavity of the housing. A sub-actuator is removably coupled to such projection and includes a shaped portion, a number of contacting portions and a depth. The shaped portion cooperates with a plunger to provide a plurality of operating characteristics of the operating member, including a plurality of positions thereof. Each contacting portion contacts a corresponding one of the contact elements when the operating member is disposed in a corresponding one of the positions. When the actuator subassembly is coupled to the housing, the depth of the sub-actuator occupies less than one-third of the width of the cavity.

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

H01H 23/00

US Classification:

200401

Abstract:

An operating mechanism is provided for a circuit interrupter, such as a battery disconnect apparatus, including a housing and a number of stationary electrical contacts enclosed by the housing. The operating mechanism includes a cam member and a two-bar linkage member having a first bar, a second bar, and a pivot member disposed between the two bars. A movable contact assembly includes at least one movable electrical contact, and is cooperable with the cam member and two-bar linkage member to move the movable electrical contact into and out of electrical contact with the stationary electrical contacts. An actuating assembly pivots the cam member between a first position corresponding to maintaining the movable electrical contact in electrical contact with the stationary electrical contacts; and a second position corresponding to releasing the movable contact assembly in order that the movable electrical contact is movable out of electrical contact with the stationary electrical contacts.
